Orbital TIG welding

Welding heads orbital TIG

A21 PRB
The PRB welding head is compact and easy to use as a result
of its unique pincer action which reduces setting-up times to a
minimum. The welding head is positioned and secured around
the tube with great accuracy in seconds. The PRB welding
heads are available in three sizes for tubes with outer diameters
of 17 to 170 mm.
®
Use these welding heads together with the Aristo MechTig
power sources.

Delivery includes
7 m of connection cable (current, gas, water).
